M ECHANICAL MOTOR.

SPECIFICATION forming part of Letters Patent No. 514,356, dated February 6, 1894:.

Application filed November 17, 1893. $erlal No. 491,277. (No model.)

To aZZ whom it may concern:

Be it known that I, PETAR Fnronn'rrn, a citizen of the United States, residing at Sheridan, county of Placer, State of California, have invented an Improvement in Pump-Powers; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to that class of intermediate devices designed to increase the eifb cacy of a pump by increasing the number of its strokes with relation to the movements of the initial driving mechanism.

It consists in certain details of construc-' tion which will be more fully explained by reference to the accompanying drawings, in which- Figure l is a perspective view of my apparatus. Fig. 2 is a vertical section through the guiding frame and movable slide.

The object of my invention is to enable the operator to increase the number of strokes made by the pu mp,or other connected device, with relation to the movements of the mechanism through which the power is applied. In carrying this out I employ any suitable frame-work A upon which the apparatus is mounted.

B is a crank shaft extending across the frame-work and suitably journaled thereon. This shaft has a pinion O fixed to it through which power is transmitted to rotate the shaft in one direction or the other as follows:

D is a second shaft journaled parallel with the first named one, and having upon it a segmental toothed rack E, the teeth of which engage the teeth of the pinion, so that when the segment is moved about its axis it will cause the pinion to rotate. This segment has a handle E of any desired length to produce the necessary amount of power, and it will be manifest that this handle may be. worked up and down, either by hand or other power which will produce a stroke sufficiently long to move the segment through nearly or quite the whole of its toothed circumference.

F is a curved yoke fixed to the frame which serves to limit the motion of the lever in an upward direction, and F is a bar extending across the frame to limit the motion in the opposite direction.

Upon the end of the shaft B is fixed a crank H. If desired this crank may have a single connecting rod uniting it with the pump rod or other reciprocating rod which may be made to reciprocate in suitable guides. In the present case, and in order to produce a vertical motion of the rod which is directly connected, I have shown a guide frame I suitably secured with'relation to the crank pin J. Within this guiding frame is a slide K having rollers upon its opposite corners which are adapted to travel within the guide so that the slide will move up and down in the guide with little or no friction. Transversely across this slide is a slot L, the length of which is equal to the greatest throw of the crank, and the antifrictional roller journaled upon the crank pin, fits and travels in this slot so that during a single revolution of the crank, this roller crank pin will traverse the slot from end to end as it passes from its greatest throw on one side to the greatest throw on the other,

while in its upward and downward movement it produces a vertically reciprocating motion of the slide as before described. Through the guide frame is made a vertical slot M, and through this slot the lugs N project being fitted to slide up and down loosely in the slot, and having the outer ends formed with enlargements which will keep them in place as they move. Between these lugs a yoke 0 extends. This yoke is curved outwardly in the center as shown, and has the outwardly projecting arms or forks P adapted to receive a pin by which the connecting or pump rod is united therewith.

The operation will then be as follows:- When the lever arm E is moved up and down, the segment E will be caused to rotate upon its shaft and as it engages the pinion G, the latter will be caused to rotate with a rapidity depending on its proportionate diameter to that of the segment. Thus by making the segment of large diameter and the pinion of comparatively small diameter, one movement of the segment which would cause it to traverse and engage the pinion from one end of the segment to the other, will cause the pinion and the shaft to rotate two, three or more times'as may be desired. This enables me to operate the pump or connecting rod with considerable rapidity while the lever through which power is applied receives a much slower motion.

. Having thus described my invention, what said crank pin, a yoke at the outer side of I claim as new, and desire to secure by Letters the guide way, bolts extending through the Patent, is vertical slot and securing said yoke to the 1 The herein described power apparatus concross head, and a rod connected with theyoke 5 sisting in a frame, a shaft mounted thereon for transmitting the power to the device to and provided at one end with a crank havbe operated,substantiallyas herein described. ing a crank pin, a pinion on said shaft, a In witness whereof I have hereunto set my toothed segment meshing with said pinion hand.
